<p><P>PROBLEM TO BE SOLVED: To provide a method of guiding a moving body in a 2-D or 3-D system and positioning the same, without needing a specific radio wave source regarding the navigation method which uses a radio wave reflector with a Runeberg lens. <P>SOLUTION: The radio wave reflector, with the radio wave reflector arranged on the surface of the Runeberg lens, is provided as a standard radio wave reflector and a reference radio wave reflector. On a plane which contains the course of the moving body, the standard radio wave reflector is provided. On a perpendicular line crossing the course plane, and apart from the standard radio wave reflector, a pair of reference radio wave reflectors which keep a fixed distance to each other are provided. The moving body transmits a fixed type radio wave; receives a reflected radio wave (standard signal) from the standard radio wave reflector and reflected radio waves (reference signals), reflected from the pair of reference radio wave reflectors; measures each delay time; and detects the 2-D position of the moving body and its deviation from the course. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
